✅ Answer: Option 3 — (13, 91, 7)

Explanation:

We are given two sets of numbers:

(5, 80, 16)

(18, 108, 6)

Let’s denote each set as (A, B, C)
We are to find a logic or formula that connects A, B, and C.

Step 1: Check the relationship in each set

For (5, 80, 16):

Check if:
A × C = B
→ 5 × 16 = 80 ✅

For (18, 108, 6):

→ 18 × 6 = 108 ✅

So the rule is:

First number × Third number = Middle number
i.e., A × C = B

Step 2: Apply this rule to each option:

🔹 Option 1: (15, 185, 14)

→ 15 × 14 = 210 ≠ 185 ❌

🔹 Option 2: (17, 8, 135)

→ 17 × 135 = 2295 ≠ 8 ❌

🔹 Option 3: (13, 91, 7)

→ 13 × 7 = 91 ✅
✔️ This matches the rule.

🔹 Option 4: (9, 81, 8)

→ 9 × 8 = 72 ≠ 81 ❌

✅ Therefore, only Option 3 — (13, 91, 7) correctly follows the same pattern:

First number × Third number = Middle number

✅ Final Answer: Option 3 — (13, 91, 7)
